Struct nannou::geom::polygon::Polygon

pub struct Polygon<I> {
    pub points: I,
}

A simple type wrapper around a list of points that describe a polygon.

Fields

points: I

The iterator yielding all points in the polygon.

Methods

impl<I> Polygon<I> where     I: Iterator,

pub fn new<P>(points: P) -> Self where     P: IntoIterator<IntoIter = I, Item = I::Item>,

Construct a new polygon from the given list of points describing its vertices.

pub fn triangles(self) -> Option<Triangles<I>>

Triangulate the polygon given as a list of Points describing its sides.

Returns None if the polygon's iterator yields less than two points.

pub fn contains(self, p: &I::Item) -> Option<Tri<I::Item>> where     I::Item: Vertex2d,

Returns Some with the touched triangle if the given Point is over the polygon described by the given series of points.

This uses the triangles function internally.

pub fn bounding_rect(self) -> Option<Rect<<I::Item as Vertex>::Scalar>> where     I::Item: Vertex2d,

The Rect that bounds the polygon.

Returns None if the polygon's point iterator is empty.

pub fn bounding_cuboid(self) -> Option<Cuboid<<I::Item as Vertex>::Scalar>> where     I::Item: Vertex3d,

The `Cuboid that bounds the polygon.

Returns None if the polygon's point iterator is empty.

Trait Implementations
